Organic search, also known as natural search, refers to unpaid search results. In contrast to paid search results (pay-per-click advertising), which are populated via an auction system, organic search results are based on relevance to the user’s search query, links and domain authority and other organic ranking factors.

Organic search refers to the search results of a search engine that cannot be influenced by paid advertising. Organic search results are ranked according to their relevance to the search term. Organic search results therefore do not include adverts, but can include search snippets such as maps, images.
